Compression ratio (varying)

The compression ratio can be increased through …- material loss from the cylinder head (planing),- a thinner head gasket,- more compression of the piston,- longer con-rods.

s sh = - old - 1 new - 1

s · (old - 1)new = - 1 s - h · (old - 1)

Height difference

A positive value for the difference in height means that either from the cylinder head must be removed material or a thinner head gasket must be used. A negative height difference will probably only be achieved with a thicker head gasket. 06/14
